chore: fix 154 f-strings, simplify getattr/URL patterns, remove dead code

[teknium1]

Summary

Three categories of mechanical cleanup, all zero-behavioral-change.

30 files changed, 173 insertions(+), 170 deletions(-)

1. F-strings without placeholders (154 fixes, 29 files)

Converted f'...' to '...' where no {expression} was present. Identified via pyflakes, fixed with a targeted regex script, compile-verified every modified file.

Heaviest concentrations: run_agent.py (24), cli.py (20), honcho_integration/cli.py (34), hermes_cli/tools_config.py (10), hermes_cli/setup.py (10).

2. Simplify defensive patterns in run_agent.py

getattr cleanup: Added explicit self._is_anthropic_oauth = False initialization before the api_mode branch in __init__, then replaced 7 defensive getattr(self, '_is_anthropic_oauth', False) calls with direct self._is_anthropic_oauth access.

URL detection helpers: Added _is_openrouter_url() and _is_anthropic_url() methods, replaced 3 inline "openrouter" in self._base_url_lower checks. Intentionally left checks on local variables (not self._base_url_lower) unchanged — those have different semantics.

All run_agent.py changes done one patch at a time with py_compile verification after each.

3. Dead code removal (small files only)

• hermes_cli/claw.py: removed unused total computation
• tools/fuzzy_match.py: removed unused strip_indent() function and pattern_stripped variable
